Yea, I'll post some pics tonight when I get off work, got to get some sleep now, got off work at midnight and it's now 6 AM :L:

3mph might be too slow, not enough wheelspin makes you rely on your tires getting a perfect hold. Not saying it's not good for your application or is bad, but my Clod with dual Integy 55t motors and 9t pinions hits maybe 6mph, and it just barely has the wheelspin to get up stuff. Granted, it's still hard for it to get stuck, but if I were you, I'd go with the "high" range.

Stayed late after work tonight and got my axles designed and drawn up. Gonna start cutting aluminum tomorow night.

Here is a pic of the planetary

Looks a bit big and beefy, might wind up being heavy, but I think that'd be better for durability instead of light and weak.

The outside of the case is about the same size as a 540 motor can. It's gonna be a whole lot smaller than an emaxx or other transmision. I'm gonna put two gears the same size out the end of it so I can have the driveshaft run parallel right under the motor and planetary to the front and rear driveshafts.
